| Test measures | F1 | F2 | F3 | F4 |
|---|---|---|---|---|
| Language/verbal attention | Visuospatial cognition | Perceptual-motor speed | Perceptual attention | |

| TPT (memory) | 0.065 | 0.774 | −0.035 | −0.043 |
| TPT (time – total) | −0.086 | 0.658 | 0.311 | 0.027 |
| Trail Making Test—Part A | 0.031 | 0.007 | 0.832 | −0.042 |
| Trail Making Test—Part B | 0.249 | 0.039 | 0.629 | 0.071 |
| SPE (right side) | 0.036 | 0.071 | −0.024 | 0.693 |
| TFR (right hand) | −0.032 | −0.056 | 0.157 | 0.587 |
| Seashore Rhythm | 0.294 | 0.053 | −0.010 | 0.285 |
Note: EFA = Exploratory Factor Analysis; HRB = Halstead-Reitan Battery. Light gray-shaded areas indicate loadings ≥ 0.24 (i.e., items with more than 5% overlapping variance with the factor); and dark gray-shaded areas indicate loadings ≥ 0.4 considered priorities for factor interpretation.
